Folks - this thread was already closed. Please no more WWV posts.

Sorry don't agree at all. Emergency communications when everything is down
and people need help is not comparable to a transmitter that puts out the
time according to an atomic clock over radio. You can always use a sundial,
and knowing the time to the second is not necessary in an emergency.

I don't think John was implying people didn't have or use wwv clocks, but
that's it not a reason by itself for WWV, and I agree with him. Why pay
thousands of dollars to staff and run wwv just for clocks and stuff? With
the internet and phones that use data and or GPS satellites to constantly

Neither GPS signals nor the 60 kHz WWVB signal are receivable inside my
apartment

Hi Roger,
I spent most of my 4-year USCG career on LORAN-C related activities. 6 months
ET school at Governor's Island, a year at the monitor station in Bermuda (yeah,
that was tough) and finally two years at the engineering center in Wildwood, NJ
(even tougher :)
I really despised the
Ah! LORAN C. I remember it well.

I doubt that. LORAN A and C were pulse systems with high peak power
[some LORAN C stations fed over a megawatt peak to the antenna], but the
average power was much lower. Before LORAN C's demise, a handful of
stations were fitted with Accufix transmitters by Megapulse Corporation

I think the millions of people who bought "atomic clocks" with no
technical background, no idea of how they set themselves would disagree.
... but only once they realize their "atomic clocks" are far less accurate.
The technology is attractive. You put in a battery, set the time zone
and it

I'm wearing an "atomic watch" as we speak and have two such clocks as well.
A few years ago I had a 4:3 Sony Trinitron tv. It was obsoleted by newer
better technology and I now have a 16:9 ratio TV just like you do. The
clock/watch argument in the age of GPS, network and cellular time sync is a
John, you're simply incorrect. Our house has a number of WWVB synched
clocks, as do many, many thousands of others.
